Gradle在运行cordova android build时使用了错误的JAVA_HOME

Question

操作：我遇到了这个问题，似乎处理了同样的问题，我有。不幸的是，我的usr/bin/gradle文件中没有export java_home=/usr/lib/jvm/default-java行。

我的错误显示java_home=/usr/lib/jvm/java-7-openjdk-amd64/jre

但是echo$JAVA_HOME返回/usr/lib/jvm/java-8-openjdk-amd64/jre

我尝试在真实的JAVA_HOME和gradle试图使用的一个符号链接之间创建符号链接，但gradle试图使用的一个符号链接不是真实的，因此我得到错误ln:failed to create symbolic link'/usr/lib/jvm/java-7-openjdk-amd64/jre':No such file or director

我试着在gradlew文件周围挖掘，发现了我认为可能是违规代码，但我不是100%确定它是如何工作的，而且当我编辑文件并执行cordova run android时，我的所有更改都被抹掉了。

这是我在Gradlew找到的代码：

# Determine the Java command to use to start the JVM.
if [ -n "$JAVA_HOME" ] ; then
    if [ -x "$JAVA_HOME/jre/sh/java" ] ; then
        # IBM's JDK on AIX uses strange locations for the executables
        JAVACMD="$JAVA_HOME/jre/sh/java"
    else
        JAVACMD="$JAVA_HOME/bin/java"
    fi
    if [ ! -x "$JAVACMD" ] ; then
        die "ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation."
    fi
else
    JAVACMD="java"
    which java >/dev/null 2>&1 || die "ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation."
fi

首先，Java home应该看起来像/usr/lib/jvm/java-8-oracle，没有“jre”部分。其次，它应该放在/etc/profile文件中：

export java_home=“/usr/lib/jvm/java-8-oracle”

导出路径=$JAVA_HOME/bin:$PATH
